Harry Potter Fans Have A Lot Of Questions After THIS Character Was Revealed In Fantastic Beasts 2

Obviously a very large spoiler warning for the upcoming film.

Once again, a big ol' spoiler warning for Fantastic Beasts: The Crimes Of Grindelwald, so if you don't want to be spoiled maybe go read one of our Bachelorette recaps, or just scream into the endless void of space!

Okay, that's out of the way. SO, in the lead-up to the film's release, a longer cast list was released and some eagle-eyed fans noticed a familiar name:

Minerva McGonagall.

Yep, one of our favourite Hogwarts professors will be making a cameo in the film, but the same eager fans who clocked McGonagall's name on the cast list also noticed that her inclusion opens up a major error... According to JK Rowling's own timeline, McGonagall wouldn't have been born yet.
